zinone direction due to theirmomentuni and the 'one way connection withthe pinion.

As shown in'Fig. 1, the rack 25-is at its depressed position 'and itwill. be noted that vtile-upper part ofthe' rack has a slpt 18 partlyexposed and partly within the sleeve '23'for' the purposes ofpo'uri-ngoil o n the working parts ofthe mechanism; As shown on Fig.4, the edgesofthe sleeve 23 form a a channel forguiding'the' oil poured in the .slot181 downward on the rack.

I have discovered that'very useful results areattained when the amountof"enga-ge- .ment ,ofthe toothed actuator 10 with t wear piece 9 on thediaphragm 8 is so re lated-that it will displace the diaphragr'n' o adistance of aboutone tenth o-f the distance to which the diaphragm maybe displaced before reaching its elastic limit I have found that thisengagement for a diaphragm having a vibrating area of about five inchesin diameter and a thickness of about one sixty-fourth of an inch, isaboutone hundredthof an inch.- It is known that the power for displacinthe diaphragm increases with theamp 'tude of the displacement. 1 havefound that with the displacement of, one hundredth of an inch the weightof member 11 may be made about one pound,"

and with such weight, .I have found that; when operatingthe device;steady sound of approximate even pitch is producedwith v very littleexpenditure of power. 1

It will be understood, that the fly-wheelof onepound-moving at aperipheralvelocity of one foot per second will develop the proper powerfor displacing- .thedia'phragm about one tenth of the distance it may beWhatfI claim is apinion for driving sald" actuator, a one-way said,rackoextending-across said A j-with v e s projecting beyond thewallsof'said casing and caps inclosing the'endsoffsliid sleeve connegtod-i of fl i g f a sig'nalfhorn, 'the -eombinationfof, a:
